In datasheet I see: Connection voltage SO + SO- max. 30 V DC
And digital inputs are up to 20V. So I guess no. Maybe resistor voltage divider?
you can add a 510om resistor to the INPDx input and it should be ok
Pulse output SO + SO- open collector
so voltage and current is not important in this case, no?!
~open collector~ no voltage provided, voltage you must supply....
Hoped I'm not OFF-TOPIC...
